ABSTRACT In Transactional Memory (TM) if any two concurrently executing transactions perform conflicting data accesses, one of them is aborted. The transaction to be aborted is usually selected by some form of contention manager. Aborted transactions waste computing resources, and reduce performance. Ideally, concurrent execution of transactions would be ordered to minimize aborts, but such an ...

Cloned bovines have a much higher abortion rate than those derived in vivo. Available evidence indicates that inappropriate epigenetic reprogramming of donor nuclei is the primary cause of cloning failure. To gain a better understanding of the DNA methylation changes associated with the high abortion rate of cloned bovines, we examined the DNA methylation status of a repeated sequence (satellit...

Ewe abortion and neonatal mortality are serious problems to sheep farmer. The objective of this paper was to report isolation of Erysipelothrix rhusiopathiae from aborted fetuses in a flock in Tehran, Iran. Abortion occurred in 10% of ewes in the flock. The fetuses were well developed and pinpoint, necrotic-like lesions were recorded on the placental cotyledons, whilst the inter -cotyledonary a...
